Web Style Sheets CSS tips & tricks

Alternative style sheets

A document doesn't need to have a single style sheet. You can
give it a default style and any number of alternatives for the
reader to choose from. This page, for example, has as alternatives
all the W3C Core Styles,
plus two style sheets found elsewhere on the Web (author: David Baron).

How the reader can select the alternatives depends on the
browser. Not all browsers yet offer a menu for it, but many do.
E.g., in Opera, Internet Explorer and Firefox you can find the
styles under the “View” menu. As of 2012, Chrome requires an
extension (e.g., Decklin
Foster's Style Chooser).

To include extra style sheets, it suffices to add more
<LINK> elements in the header, with the right REL and TITLE
attributes, as follows. (I left out some of the styles; see the
source of this document for even more links.)
